    <!-- Behavior -->
    行为
   </h2>
   <p>
    <!-- This component multiplies two values coming in via the west inputs and outputs the product on the east output. The component is designed so that it can be cascaded with other multipliers to multiply a multiplicand with more bits than is possible with a single multiplier: The carry-in input provides a multi-bit value to be added into the product (if it is specified), and a carry-out output provides the upper half of the product result, which can be fed into another multiplier. -->
    该元件将通过西边输入传入的两个值相乘，并在东边输出上输出乘积。 该组件的设计使其可以与其他乘法器级联，以将被乘数与单个乘法器可能的位数相乘：进位输入提供要添加到乘积中的多位值（如果指定） ），进位输出提供乘积结果的上半部分，可以将其输入另一个乘法器。
   </p>
   <p>
    <!-- If the multiplicand, the multiplier, or the carry-in input contain some floating bits or some error bits, then the component will perform a partial multiplication. That is, it will compute as many low-order bits as possible. But above the floating or error bit, the result will have floating or error bits. Note that if the carry-in input is completely floating, then it will be assumed to be all-zeroes. -->
    如果被乘数、乘法器或进位输入包含一些浮动位或一些错误位，则该组件将执行部分乘法。 也就是说，它将计算尽可能多的低位。 但在浮动或错误位之上，结果将具有浮动或错误位。 请注意，如果进位输入完全浮动，则将假定其为全零。
